Securing Cloud Data Storage

Innovations are necessary to ride the inevitable tide of change. Most of enterprises are striving to reduce their computing cost through the means of virtualization. This demand of reducing the computing cost has led to the innovation of Cloud Computing. One fundamental aspect of this new computing is that data is being centralized or outsourced into the cloud. Outsourcing data into the cloud is economically attractive for the cost and complexity of long-term large scale data storage, it does not offer any guarantee on data integrity and availability. The authors propose a distributed scheme to ensure users that their data are indeed stored appropriately and kept intact all the time in the cloud.
